Abstract:
An ECG waves separation technique based on math ematical morphology is suggested and discussed in this paper. Without detection of QRS complexes, the QRS complexes can be eliminated by series morphological o perations. Then the start points and end points of P-wave and T-wave can be de cided and the waves of ECG are separated qualitatively and quantitatively. The r esults of qualitative separations are rather satisfied and the SDs of quantitative separation results are not very large. Also, ECG signals are filtered and bas eline is normalized by morphological method.
